TEMPERATURE REFERENCES FOR HIGH PRECISION CALIBRATIONS
Temperature reference sensors serve as a comparison standard for calibrating other temperature sensors (test item). The reference probe and the test item are immersed in a stable heat source such as a dry block calibrator or a liquid calibration bath. All Fluke reference probes are traceably calibrated to a national temperature standard and supplied with a corresponding certificate. The main selection criteria for a temperature reference probe are the temperature measuring range and the required accuracy together with a reference thermometer.
SECONDARY TEMPERATURE REFERENCE FLUKE 5615
The reference probe 5615 is ideal for on-site calibrations in production processes. The steel-sheathed platinum resistance thermometer (PRT) with a diameter of 6.35 mm and a length of 30.5 cm is robust and at the same time meets the accuracy requirements for the calibration of temperature sensors in pharmaceutical, biotech, medicine and food applications (freezers, freeze dryers, incubators, sterilizers / Autoclaves, hot air applications).
- Temperature range –200 °C to 420 °C
- Calibrated accuracy ± 0.012 °C at 0 °C
- Maximum immersion depth: 25.4 cm, diameter 6.35 mm
- Comes with a traceable docking certificate
FLUKE 5626 FOR HIGHLY PRECISE CALIBRATIONS
The Fluke 5626 reference probe is suitable for calibrations with higher accuracy requirements. The 100 Ohm platinum resistance thermometer (Pt100) has an accuracy of ±0.006 °C at 0 °C. The Fluke 5626 PRTs have a temperature range of –200 °C to 661 °C and are suitable as excellent working or test refrences for calibrations in high temperature applications, such as drying and hardening processes in the medical, aerospace and automotive industries.
- Temperature range –200 °C to 661 °C
- Calibrated accuracy ±0.006 °C at 0 °C
- Immersion depth: at least 12.7 cm is recommended
- Comes with a traceable calibration certificate
FLEXIBLE TEMPERATURE REFERENCE FLUKE 5606
The 5606 reference probe is 50 mm long and comes with a lead cable of 2.4 meters, which can be completely immersed over the entire temperature range. The reference probe can therefore be used in non-corrosive liquids or in dry media in the range from -200 °C to 160 °C. the temperature reference 5606 is also suitable for use in the dry block calibrator Fluke 9142 or Fluke 9170 series , especially when short temperature sensors are calibrated. The reference probe can be used at the same immersion depth as the test probe, which increases the calibration accuracy
- Temperature range –200 °C to 160 °C
- Calibrated accuracy ±0.05 °C
- Metal jacket: L 50 mm, Ø 3.1 mm
- sensor length and position: L 30 mm, 3 mm from measuring tip
- Maximum immersion depth: entire cable length of 2.4 meters
REFERENCE TEMPERATURE SENSOR FOR SPECIAL APPLICATIONS
Fluke has a wide range of PRT temperature reference probes with different temperature ranges, accuracies, diameters, lengths and designs. Angled reference probes for use in dry block calibrators enable the calibration of temperature transmitters with a large transmitter head or bulky temperature probes.

SELECTION GUIDE FOR REFERENCE THERMOMETERS AND PROBES
Industrial temperature sensors are usually calibrated by placing them in a stable temperature source (dry block, oven, calibration bath) and comparing their readings with a reference standard probe connected to a thermometer. The guide provides instructions on how to select a thermometer and an associated reference probe. Together, they must provide the accuracy required to calibrate common temperature sensors such as PRTs and thermocouples.
